Definitions
- the invention relates to a rope bottle according to the preamble of claim 1.
- the invention also relates to a method for mounting a cover to a corresponding cable bottle.
- European Patent EP 1 457 455 B1 discloses such a rope bottle in the form of a lower block for cables.
- the lower block consists essentially of a central connecting element, which combines both the function of an axis for this purpose at both ends rotatably mounted pulleys and the function of a receiving element for a load hook in it.
- the load hook is mounted for rotation about a vertical axis from below in the connecting element.
- the two pulleys are coaxial with each other and rotatably mounted. About the pulleys sheared load cables are guided, which run to the cable.
- the pulleys are provided with covers as accident protection.
- the covers are to prevent the fingers or hands of an operator between rope and pulley are fed and clamped.
- the covers According to the outer contour of the pulleys, the covers have approximately a circular disk-shaped outer shape and are divided for mounting in the axial direction of the pulleys.
- the longitudinal pitch is such that a decker-shaped outer hood part is formed that is placed laterally from the outside on the pulley until it comes to an inner hood part to the plant and is fixed there.
- the circumferential parting line of the two hood parts extends in the radial direction of the pulleys seen approximately in the region of the center of a rope groove of the pulley.
- the inner hood part is annular and formed with an outer circumferential edge on which the outer hood part comes to rest, and is an integral part of the connecting element.
- Each of the cover hoods is provided with two inlet and outlet openings so that the load rope guided around the cable pulley can enter the cover hood and exit from it again.
- the rope openings have a width which corresponds approximately to the width of the rope groove of the rope pulley and thus about 3 times the load rope diameter.
- the length of the Cable opening is based on the circumference of the pulley or the cover about 90 °, wherein in the upper part of the cover between the two inlet and outlet openings a divider remains. Assuming that the zero point of the angle data is placed at the top in the center of the cover, the first inlet and outlet opening starts at about 15 ° and runs to 105 ° and the second inlet and outlet opening extends from 255 ° to 345 °.
- the inlet and outlet openings have such a large longitudinal extent in the circumferential direction of the pulley, since the opening angle between the two strands of the load cables depending on the configuration of the cable and the distance between the cable and the bottom block can vary between about 0 ° and 30 ° ,
- the flow point of the load rope moves from the pulley in the region of the inlet and outlet openings and in the circumferential direction of the pulley.
- a cover element is used in each of the inlet and outlet openings, which closes the inlet and outlet openings except for an opening for the rope.
- This opening is only slightly larger than the diameter of the rope. This prevents that the hand or the fingers of an operator of the bottom block of the load rope can be pulled into the remaining space of the inlet and outlet opening.
- This cover is in the slot-shaped input and
- Outlet opening slidably held in the circumferential direction of the pulley in order to move parallel with the migration of the cable drain points in the inlet and outlet opening.
- the cover covers on the one hand the input and
- the cover Seen center position of the cover with respect to the inlet and outlet opening - the edges of the rope opening u-shaped inward.
- the cover consists essentially of an upper base strip, a narrow web bar and a lower retaining strip, which have an H-shaped cross section to each other.
- the cover is integrally formed as a plastic injection molded part. For an assembly of the cover this is postponed at one end of the rope and the outer hood part is at least loosen to expand the slot-shaped inlet and outlet opening for insertion of the lower retaining strip.
- the object of the present invention is to provide an improved and maintenance-friendly cable bottle, in particular a lower bottle, for cables.
- a rope bottle especially lower block for cables, with at least one of a cover hood with inlet and outlet openings for a load rope surrounded pulley, wherein in at least one of inputs and
- Outlets a cover used and held on an edge of the inlet and outlet engaging behind retaining strip in the inlet and outlet, the cover has an opening for the load rope and the opening in the cover is smaller than the inlet and outlet opening in the cover , a maintenance friendliness achieved by that
- Covering such is at least divided into a first cover and a second cover, that for a mounting of the cover on the cover, the first cover and the second cover withIdentschertem load rope with their
- the cover with its relatively small opening successfully prevents a hand or the operator's fingers can be pulled by the load rope in the cable opening of the cover.
- it is advantageously prevented by the cover, that the incoming and outgoing in the cover load rope grinds at the edge of the inlet and outlet openings of the cover and thus wears.
- the pulley is better protected against the ingress of dust, dirt and moisture.
- Outlet opening is arranged.
- the cover can be easily attached to the cover in the region of the inlet and outlet opening.
- Exchangeability of the cover when worn can be simplified, that the first cover and the second cover are detachably connected together in the assembled state.
- This releasable connection can be made in particular via a screw connection.
- a particularly simple assembly is achieved in that the cover is divided into the first cover member and the second cover member in a plane which is aligned in the radial direction of the pulley and in the region of the opening of the
- Cover element runs.
- a particularly long durability of the cover is achieved in that the inlet and outlet openings are slot-shaped and the cover is displaceable in the inlet and outlet opening in the circumferential direction of the pulley.
- a simple attachment of the cover to the cover is achieved in that the cover covering the inlet and outlet openings from the outside and surrounds the edges of the inlet and outlet openings with the retaining strip inwards.
- the cover element comprises a base strip, a web strip and a retaining strip, which together have an H-shaped cross-section, and the retaining strip lies with its guide surface on the Inner surface of the cover in the region of the inlet and outlet opening.
- the cover is widened at one end triangular form to a guide portion which receives the opening formed as a channel for the load rope.
- Cover part is divided and the retaining strip is arranged in the guide area on the cover.
- Retaining bar is inserted into the inlet and outlet opening along the load rope, then the first cover member is displaced in the axial direction of the pulley, so that the part of the retaining strip engages behind the associated edge of the inlet and outlet opening, then the second cover part in one of the first Cover part occupied part of the inlet and outlet opening with its part of the retaining strip is inserted, then the second cover member is moved in the axial direction of the pulley, so that the part of the
- the second cover Retaining the other opposite and associated edge of the inlet and outlet openings engages behind, the second cover is moved in the inlet and outlet opening in the circumferential direction of the pulley in the direction of the first cover, so that the parts of the opening for the load cable to a common opening , Then the first cover and the second cover are pushed towards each other in the axial direction of the pulley and are releasably connected together.
- it can be avoided to recut the load rope for assembly and to have to open hood parts for a broadening of the inlet and outlet opening.

- FIG. 1 shows a perspective view of a device according to the invention
- Bottom 1 trained rope bottle which is suspended over two pulleys 2 (see also Figure 2) guided pairs of load cables 3 to a cable, not shown.
- the lower block 1 consists essentially of a central connecting element 4 with two laterally mounted thereon pulleys 2 and a suspended from below thereto hook 5.
- the load hook 5 is rotatable about a vertical axis in a recess of the
- Bearing element 4 mounted on an axial bearing, not shown.
- the coaxially arranged and spaced apart on the connecting element 4 pulleys 2 are each surrounded by covers 6, which are seen in the axial direction of the pulley 2 divided into an outer hood part 6a and an inner hood part 6b in the plane of the pulley 2.
- the two hood parts 6a, 6b are identical.
- the outer hood part 6a and the inner hood part 6b are each as flat annular discs with an outer circumferential and
- the outer hood part 6a and the inner hood part 6b are thus dish-shaped or dish-shaped.
- the outer hood part 6a abuts with its edge 6c on the edge 6c of the inner hood part 6b.
- the two hood parts 6a, 6b thus limit a flat cylindrical cavity for receiving the pulley 2.
- the correct angle mounting the two hood parts 6a, 6b to each other is facilitated by a centering, which is inserted into corresponding recesses in the edges 6c of the hood parts 6a, 6b.
- the cover 6 see also Figure 4 are each two inputs and
- Outlet openings 7 for the inlet of the load rope 3 on the pulley 2 and its outlet from the pulley 2 are arranged. These inlet and outlet openings 7 have in the circumferential direction of the pulley 2 and the cover 6 seen a length L, which corresponds to a multiple of the diameter of the load cable 3 and are thus slit-shaped. The length L corresponds to one sixth of the circumference of the cover 6. This length L is required because - as in the
- the thus relatively large inlet and outlet openings 7 are each at least partially closed with a cover 8, which has an opening 9 for the implementation of the load cable 3 of the pulley 2 or to the pulley 2.
- the inlet and outlet openings 7 are each completely from the lower block 1, in which an operator works with the lower bottle 1, the inlet and outlet openings 7 are each completely from the lower block 1, in which an operator works with the lower bottle 1, the inlet and outlet openings 7 are each completely from the
- Covering element 8 closed. A few meters before the highest raised position of the lower block 1, when the dreams of the load cables 3 are then spreading, the cover elements 8 are moved in the circumferential direction U downwards and each release an upper part of the inlet and outlet openings 7. Since no operator works in the raised position with the lower bottle 1, in terms of safety, the partial release of the inlet and outlet openings 7 is safe.
- the opening 9 for the load rope 3 is slightly larger than the diameter of the load rope 3 and has a rectangular cross section with rounded corners whose width and length are in a ratio of 2: 1 to 3: 1 to the diameter of the load rope 3. This ensures that the risk of the operator Pulling his fingers or hands by the incoming load rope 3 in the inlet and outlet openings 7 is considerably reduced.
- the drain point 10 of the load cable 3 of the pulley 2 the cover 8 in the circumferential direction U of the cover 6 between an upper and a lower end positions back and forth.
- the cover element 8 consists essentially of a correspondingly to the edges 6c of the cover 6 circular curved upper base bar 8a, the surface on the outer surface 6d of the hood parts 6a, 6b in the region of the edges 6c of the hood parts 6a, 6b rests.
- the base strip 8a thus covers each of the inlet and outlet openings 7.
- the base strip 8a extends approximately from the center in such a way that a guide portion 8b for the load rope 3 in the form of a substantially right triangle, corresponding to the edge 6c of the hood parts 6a, 6b curved hypotenuse is formed by the base strip 8a.
- the base bar 8a is flat and strip-shaped. Also, it can be seen from Figure 1, that the opening 9 is formed for the load cable 3 in the cover 8 as a channel 9a extending from the base bar 8a to an upper of the two outer Catheter sides of the guide portion 8b extends.
- the longitudinal extent of the channel 9a extends in the plane of the pulley 2 at an angle of 90 ° to an imaginary line passing through the drain point 10 of the load rope 3 from the pulley 2 and the center M of the pulley 2.
- the lower block 1 for easier handling by the operator has an upwardly open and horizontally extending recessed grip 1 1 in the region of the connecting element 4, whose width corresponds to the distance between the two covers 6.
- Cover part 8f and a second cover part 8g is divided. This division is in
- the first cover 8f has a width of 2/3 of the width of the cover 8 on.
- the first cover 8f is shown in section in Figures 2 and 3.
- the division of the cover element 8 makes it possible to insert the first cover part 8f into the inlet and outlet opening 7 in a first assembly step and to lock it there in a second assembly step by inserting the second cover part 8g into the inlet and outlet opening 7.
- the second cover member 8g is detachably attached to the first cover member 8f.
- Figures 2 and 3 each show a sectional view through one of the two
- the load cables 3 are not shown.
- the two cover elements 8 are each arranged in a so-called normal position in the inlet and outlet openings 7, in which the
- the lower block 1 hangs in the area of an operator who preferably guides and / or directs the lower block 1 on the handle 11.
- the inlet and outlet openings 7 are each completely covered by the cover 8.
- the channel 9a of the opening 9 runs almost vertically and thus parallel to the load cables 3.
- the inner wall of the channel 9a located inwardly towards the pulley 2 engages the side of the load rope 3 facing the opposite load rope 3, since the cover element 8 is displaceable relative to the inlet and outlet openings 7 in the circumferential direction of the cover 6 is guided.
- the occurring friction between the load cable 3 and the channel 9a of the cover 8 is low, since the cover 8 is very light.
- the cover 8 is made as a plastic injection molded part made of a material having a high wear resistance.
- FIG. 3 shows the two cover elements 8 in a position similar to that in FIG. 2
- a single cover 6 is shown without a cover 8 in an orientation of a vertically hanging on the cable lower block 1.
- the front and rear of the bottom block 1 and has been selected perpendicular to the axis of rotation of the pulley 2, so that one of the inlet and outlet openings 7 is clearly visible.
- the inlet and outlet opening 7 has the shape of an elongated rectangle with rounded ends.
- the width B of the inlet and outlet opening 7 corresponds approximately to 2 to 3 times the diameter D of the load rope 3 and the length of the inlet and outlet opening 7 corresponds approximately to 10 to 15 times the diameter D of the load rope 3 or about one sixth of the circumference of the cover 6th
- Figure 4 shows in connection with Figure 2 or 3, that based on the peripheral surface of the cover 6 and the assumption that at the uppermost point of the cover 6, the angle is set to 0 °, the first inlet and outlet opening 7 about starts at 40 ° and runs to 100 °, the second inlet and outlet opening 7 on the opposite side begins in the range of 260 ° and ends at 320 °.
- the cover 8 is dimensioned with respect to its length so that in its extremely shifted upward normal position, the lower end of the input and

- FIG. 5 shows that the cover element 8 covers the edges of the inlet and outlet openings 7 externally with its base strip 8a, which is formed at the upper end as a triangular guide area 8b.
- the cover element 8 covers the edges of the inlet and outlet openings 7 externally with its base strip 8a, which is formed at the upper end as a triangular guide area 8b.
- Guide area 8b is the base bar 8a connected via its web bar 8d with the retaining strip 8c, which engages behind the edges 6c of the inlet and outlet openings 7 (see Figure 6). Accordingly, the retaining strip 8c is attached via the central web strip 8d to the underside of the base strip 8a, so that the cover element 8 has an H-shaped cross section in this region. As a result, the cover 8 is displaceable in the circumferential direction of the cover 6 at this.
- the retaining strip 8c thus lies with its edge 6c facing the guide surface 8e on the inner surface 6e of the edge 6c. In the area of the opening 9 eliminates the web bar 8d and the
- Retaining strip 8 c is held above the web bar 8 d in front of and behind the opening 9. It can be seen from FIG. 2 that the retaining strip 8c extends over a region of approximately 30 °. The part of the base strip 8a that adjoins the guide area 8b downwards is not provided with a retaining strip 8c and a web strip 8d. A guide takes place via the remaining cover element 8 with its retaining strip 8c in the region of the guide region 8b.
- FIG. 6 shows a further sectional view of FIG. 4, the section being laid through the axis 13 of the pulley 2.
- the axis 13 is part of the
- the pulley 2 is mounted on a bearing 14.
- the axis 13 or the connecting element 4 serves to the circular inner and outer hood parts 6a, 6b, as sheet metal parts are designed to support.
- the inner hood part 6b which is first pushed onto the axle, is supported on a shoulder 13 bounding the axle 13
- annular outer hood part 6a is closed in the region of the axis 13 by a circular cover 19. Furthermore, it can be seen that the base strip 8a is strip-shaped in cross-section.
- FIG. 7 is a perspective view of a first cover part 8f of FIG.
- Covering element 8 shown outside of a lower bottle 1 and thus in a non-assembled state. As described above, the first cover member 8f is in
- Covering 8 seen the upper part of the base bar 8a to a
- triangular guide portion 8b widens or passes into this.
- the lower part of the base strip 8a remains flachformig and begins in the circumferential direction of the cover 8 seen in the middle in cross-section U-shaped, in which the edge strips 8h laterally adjoin the edges of the base strip 8a.
- Edge strips 8h decrease in the direction of the lower end of the base strip 8a and are no longer present at the end of the base strip 8a.
- reinforcing ribs 8i extending parallel to one another and spaced from one another on the inside of the base strip 8a are provided for the base strip 8a in order to ensure reliable covering of the inlet and outlet openings 7 and to save material.
- the width of the reinforcing ribs 8i decreases like that of the edge strips 8h in the direction of the lower end of the base strip 8a.
- the opening 9 for the load rope 3 can be seen.
- flat cylindrical nubs 12 are arranged in a grid shape, which projects from the first parting surface 8j.
- a cylindrical bore 16 for a screw 17 is provided in each case.
- the bore 16 extends with its longitudinal extent parallel to the axis of rotation of the pulley 2.
- the figure 7 shows that at the bottom of the base bar 8a in the area adjacent to the opening 9 and in the circumferential direction of the cover 6 extending the web bar 8 d with the retaining strip 8 c connect.
- the retaining strip 9c is continuous. It can be seen that the retaining strip 8c has only about 1/3 of the length of the cover 8 and thus the guidance and displacement of the cover 8 in
- Circumferential direction of the cover 6 is possible.
- the opening 9 is not tubular but open groove-shaped.
- FIG. 8 is a perspective view of a second cover part 8g of the cover member 8 provided to cover the first cover part 8f
- the second cover part 8g is shown mirror-inverted, in order to also have a view of a second cover part 8g
- the first separation surface 8j of the first cover part 8f and the second separation surface 8k of the second cover part 8g are in contact with each other.
